I have about 132,000 miles on my truck and I have owned it since June. When I got the truck, it would shift roughly when cold and improved a little when at full running temp. I switched over to Amsoil Syncromesh fluid fearing maybe the previous owner put the wrong fluid in there and the syncros where starting to wear. Anyways, swapping the fluid made the truck shift better all around. Last weekend I was driving through the mountains when we came to a small town and pulled off to stop. I pushed in the clutch and noticed it felt harder to push in. Also seemed to go in and out of gear harder too. This week I am experiencing the same sort of issue. Could this be my hydros going out? I have searched on here and it seems some people have had similar problems when the master or slave cylinders start to go. Is upgrading to the south bend kit worth the extra money? Thanks for the help TDR members.
